CHARLES E. BONINE, OFJ PHILADELPHIA, PENNSYLVANIA, ASSIGNOR -TO THEELECTRIQ SERVICE SUPPLIES COMPANY, OF PHILADELPHIA, PENNSYLVANIA, ACORPORA TION OF NEW JERSEY,-

To all whom it may concern:

Be it known that I, GHA'RLEs E. Bonnie. of Philadelphia, in the county,of Phila delphia and State of Pennsylvania, have invented certain newand useful Improvements in Signs for'Railway-Cars, whereof the followingis a specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in signs, and moreespecially that class of signs which are used in connection with railwaycars in order to give notice of the prospective stations or streets,although it is obvious from certain aspects of the invention, that thesame may be used for other purposes.

The invention has more particular relation to the means for operating anelongated flexible curtain containing a series of names, which curtainmay be wound upon one roll and unwound fromthe other, so that the namesmay be successively displayed.

An object of the invention is to provide a mechanism for operating therollers on Which the flexible curtain is mounted, which means shall bepositive in its action and durable in construction, and wherein eitherone or the other of the rollers is always. in operative connection with:the operating means. i

The invention consists in certain 'constructions and 'in' certain parts,improvements and combinations, hereinafter more fully specified.

In the drawings which showby way of illustration one embodiment of myinven tion, Figure I, is a partial front view, and a partial verticalsectional View of my improved device. Fig. II, is a sectional view onthe line II, II, of Fig. I. Fig. III, is a sectional view on the lineIII, III, of Fig.

SIGN FOR RAILWAY-CARS.

and a downwardly projecting portion 8, at

the front of the casing. The bottom piece 6, is provided with similarparts 9, and 10.

An angle piece 11, is secured to the top metal piece 5, of the casing,and spaced from the flange 7, so as to 'form--'a pocket or recess 'for aglass plate 12, forming the back of the casing. A similar angle piece11, is attached to the bottom metal piece 6,

and forms a pocket for-theibottom (edge of the glass plate 12.Angle-pieces 11, are also attached to'the top and' bottom port-ions ofthe casing at points adjacent the front thereof, so asto form recessesor pockets for the front glass plate 13.

' The projecting members 8, and 10, extend at some distance from thebottom and top portions, so as'to partially close the front of thecasing. These features form no part of the present invention and are,therefore, not claimed herein,

The flexible curtain or sign' 14, is attached at one end-to a roller'15, and at its other end to a roller 16. The rollers 15, and 16,

are journ'a led in the end plates-2, and 3. At

the right hand end of the casing, as viewed extends in a verticaldirection, arid-has its I end of the shaft 21, has a collar 24, attachedthereto in any suitable way. The hub 20, is locatedbetween the collar24, and the bearing 22, which prevents endwise movement of the hub onthe shaft 21. and holds the gear wheel 19, in mesh with the gear Wheel18. The roller 16, carries a beveled gear wheel 25, which meshes with abeveled gear wheel 26, also loosely mounted on the shaft 21, and held inmesh with the gear wheel 25, by the bearing 23. The gear wheel 26,carries the hub 27. The shaft 21, may be turned by a hand crank 28.

The shaft 21,-is provided with a longit-udinal groove or recess 29, (seeF1g. II), which extends from a point ad acent the hub 27, to a pointadjacent the collar 24. Mounted within the groove or recess 29, 1s apawl 30, which is pivoted at 31, to the shaft 21. The hub 20, of thegearwheel 19, is provided with a recess 32, which is formed with aradial shoulder 33, and a spiral shaped curved surface 34, extendlngfromthe bottom of the recess 32, to and ownedin with, the inner curvedsurface of the hdb The hub 27, (see Flg. VI has a similar recess 35,which has a radial shoulder 36, and a curved surface 37, simllar to thesurface 34. The curved surface 37, how ever, is located on the oppositeside of the recess from that of the curved surface 34.

The locking pawl 30, is so constructed that when the end 38, whichcooperates with the hub 20, is housed within the recess or groove in theoperating shaft 21,the opposite end 39, of the pawl 30, which cooperateswith the hub 27 is thrown out of the recess or groove in the operatingshaft to more or less extent. When the recess 35, is brought oppositethe end 38, of the pawl 30, as shown in Fig. VI, said pawl may be movedoutward into the recess, and the face of the pawl will engage theshoulder 36, on the hub 27 and if the shaft 21, is rotated in thedirection of the arrow, Fig. VI, it will cause the hub27, and gear 26,to rotate therewith, and thus impart a rotary movement to the roller 16,through the gear 25. When the shaft 21, is rotating in the direction ofthe arrow in FigJVI, it is also rotating in the direction of the arrow,as shown in Fig. V, relative to the hub 20. This will cause the upperend 38, of the'pawl 30, to move away from the shoulder'33, and theinclined surface 34, will crowd the same back into the recess or groovein the main shaft 21, and said main shaft 21, will rotate freely withinthe hub 20.

Let us suppose the parts are in the position shown in Figs. V, and VI,and the operating shaft 21, is turned in the opposite direction. The end39, of the pawl 30, will then be carried along the inclined surface 37,and said end gradually move into the recess or groove in the shaft 21.Inasmuch as the pawl 30, is made in one piece and pivoted at 31, theother end 38, of the pawl will be raised out of the groove or recess inthe shaft 21, and will contact with the shoulder 33, formed in the hub20, and positively lock the hub 20, to the shaft 21, so it will.

be rotated thereby, and through the gear 18, positively rotate theroller 15. Of course, as the roller 15, is rotated, the flexible curtainbeing wound thereon, will cause the roller 16, to be rotated by theunwinding of the curtain therefrom, and through the gear 25, the hub 27,will loosely rotate. on the shaft 21, and allow' the unwinding of theflexible curtain from the roll-er 16. It will readily be seen,therefore, that I have provided a mechanism whereinby the simplerotation of the operating shaft in one direction or theother, one rolleror the other will be locked to the operating shaft, and

caused to rotate therewith.

The flanges 4, of the end plate 3, project sufficiently far to house theoperating shaft 21, and a metal plate may be attached to the outer edgesof the flanges 4, so as to completely inclose the operating mechanism.The end plates 2, and 3, as clearly shown in Fig. IV, may also beprovided with projecting flanges on their inner faces to rcceive'theglass plates 12, and 13.

It is obvious that minor changes in the details of construction may bemade, with out departing from the spirit of my inven tion, as set forthin the appended claims.

I claim 1. The combination of sign rollers and a flexible sign mountedthereon; of gears mounted on the shafts of said rollers; a driving shaftextending at right angles to the axes of said rollers, and driving gearscarried by said driving shaft and engaging respectively the gearscarried by the rollers; means for holding the driving shaft from endwisemovement, means for rotating said shaft; a pawl extending longitudinallyof the driving shaft and cotiperating with said driving gears, and meanswhereby said pawl is caused to engage one of the driving gears when saiddriving shaft is rotated in one direction and for causing said pawl toengage the other gear when said driving shaft is rotated in the oppositedirection.
